Overed in the room. And through simulation test to the room in the method, the article obtains the wireless transmission model in room to carry on the confirmation to this model.Afterwards, carrying on the analysis to the edge field intensity, and determined the edgeantenna installment position. In the choice cover plan process, introduced each kind of supply oscillator use environment and determined the supply oscillator type. Explaining the distributed system, the optical fiber distribution system and so on several distributed ways. On the comparison, it had determined cover ways which the place was suitable. Through a series of improvements, the article has obtained the plan which is finally used, the antenna, the primary device, the skeleton line amplifier and so on. Afterompleting the room covers, in room distribute system will inevitably change the big net original cover situations.

通过对楼内场强进行现场DT测试，归纳出了信号在室内覆盖的薄弱环，并由此对边缘场强进行了分析，确定了边缘天线的安装位置；在选择覆盖方案的过程中，介绍了各种信号源的使用环境，针对各个场所内的电磁环境、场所的结构、楼层高度等各自不同的特点，业主对覆盖提出的不同要求，确定信号源的类型；对天馈分布系统、光纤分布系统等几种分布方式进行了比较，确定了该覆盖场所所适用的方式：通过一系列的方案组合，对几个不同的方案，根据楼域的结构以及业主的要求进行改进，归纳出了最终所采用的方案，由此确定了天线、元器件、干线放大器等的布放位置。

The 12m American households with television sets that use rooftop or rabbit-ear aerials to pluck television signals from the ether will need a converter box to receive the new all-digital broadcasting.
